Abstract: A device for conditioning the lubricating oil of a torque transmission device for motor vehicles, in particular for gear transmissions, in which the lubricating oil is heated at least temporarily in the cold state in order to reduce friction and/or churning losses. For an improved reduction in the losses in the cold running range, it is proposed that at least one heating element be disposed directly in the oil-lubrication flow of the transmission elements.

Abstract: A drive device includes a first drive unit and a second drive unit. A transmission unit includes a primary shaft for connection to the first drive unit, a secondary shaft, and at least one gear pair via which the primary and secondary shafts are operatively connectable to one another. Mounted in coaxial relationship to the secondary shaft is a driving gear which is operatively connected to the second drive unit, and mounted in coaxial relationship to the primary shaft is an output gear which meshes with the driving gear. A secondary-shaft coupling device can couple the driving gear directly with the secondary shaft, and a primary-shaft coupling device can couple the output gear directly with the primary shaft.

Abstract: A drive arrangement for a hybrid-drive motor vehicle includes an internal combustion engine and at least one electrical machine which, via a speed-change gearbox having a plurality of gear ratios, provide, alternately or together, an output drive to at least one axle differential of the motor vehicle. The internal combustion engine can be uncoupled by a disconnecting clutch. The gearbox is divided into two sub-gearboxes, with the internal combustion engine being connected for drive to the first sub-gearbox such as not to be able to be uncoupled. The electrical machine is arranged, in the path along which force is transmitted, downstream of the disconnecting clutch arranged at the output of the first sub-gearbox but upstream of the second sub-gearbox. The output of the second sub-gearbox provides an output drive to the axle differential.

Abstract: A cooling system for a high density power motor, in particular an axial-flux electric motor, wherein a pump is directly fitted in an axial position on the output shaft of the electric motor and feeds at outlet a flow of liquid coolant directed towards a first heat exchanger coupled to a power electronic supply circuit of said motor; the first heat exchanger having at least one outlet from which the liquid coolant is fed to a second heat exchanger coupled to the windings of the electric motor for cooling the electric motor itself; the cooling system carrying out in succession removal of the heat from the power electronic supply circuit and then from the electromagnetic part of the motor.

Abstract: A vector control method for electric motors, characterized in that it comprises the steps of: supplying a reference vector (VoutMAX); supplying a required vector (Vf), preferably represented by means of a real vector component (Vq) and an imaginary vector component (Vd); comparing the magnitude (VMAX) of said reference vector (VoutMAX) with the magnitude of said required vector (Vf), generating at least one result (V6, index_clip) that expresses the relationship existing between said magnitudes; generating a reduction value (J) as a function of the result (V6, index_clip); and generating a clipped value (VfCLIP) by limiting the magnitude of the required vector (Vf) as a function of the reduction value (J) and maintaining the phase of the clipped value (VfCLIP) unaltered with respect to the phase of the required vector.

Abstract: A device for driving an electric motor includes: an inverter circuit, configured for converting a d.c. supply signal into an a.c. supply signal; and a control block, connected to the inverter circuit and configured for controlling the inverter circuit by means of a pulse-width modulation, having a given cycle-period value. The driving device further includes a first random-number generator, connected to the control block and configured for supplying to the control block pseudo-random or random cycle-period values.

Abstract: A graphic tool and a method are provided, to represent corporate data in terms of know-how and intellectual property management risk and in terms of corporate functional breakdown by asset. The tool and method may be used to evaluate risk associated with events related to know-how and intellectual property management and capable of affecting or interrupt production. The tool and method also allow analysis of company production structure, for the purpose of functional or corporate reorganization.

Abstract: A device for measuring operating parameters of an electric motor includes a non-ferromagnetic disk which is solidly connected to a rotor of the electric motor and is provided with a plurality of peripheral sockets. A plurality of magnets are associated with the sockets. A pair of Hall effect sensors face the non-ferromagnetic disk on the surface of which the sockets are set. An acquisition and processing system of the signals produced by the Hall effect sensors comprises a resolver to digital converter module adapted to multiply said signals by the cosine and the sine of an arbitrary angle, to subtract the results one from the other and to process the resulting signal through a negative feedback system. The Hall effect sensors are placed so their resulting output signals are in electrical quadrature between each other.

Abstract: The present invention concerns an absolute position sensor based on the use of Hall effect sensors applied to the control of electric motors and mechanical shafts

Abstract: An apparatus for detecting surface defects particularly in rolled strips, the operation of the apparatus being based on the use of a telecamera with multiple sensitive elements which form parts of respective bright-field and dark-field recording channels. More precisely, the above-mentioned elements are sensitive to light radiations within respective ranges of wavelengths corresponding to those of the radiations emitted by the light sources. The latter are arranged in a manner such that, in one case, the radiation emitted thereby falls substantially tangential on the surface of the strip to be checked and, in the other case, such that the radiation reflected by the said surface is directed towards the telecamera.
